RMI IntroductionA remote method call (RMI) is the name of a program on a machine that calls a method on another machine. This gives you a general idea of what RMI is used for, but it's not quite clear. RMI is the cornerstone of a Java-supported distributed system, such as well-known EJB components. RMI is an object-oriented implementation of remote procedure call (RPC), which is implemented through socket communication and object serialization techniques. Here is a quote from Wikipedia about RMI

The bytecode instructions for the method call before JDK7 total four, invokeinterface, Invokespecial, Invokestatic, invokevirtual. These four instructions complete the invocation of all types of methods in Java.Invokeinterface (Call interface method)Unsigned number indexbyte1 and Indexbyte2 common component A current class constant Pool index (index), which is (indexbyte1Operand count is an unsigned number that is not 0. ObjectRef must be a reference

can significantly improve remote invocation performance for rest and more, and upgrade the Servlet API support from 2.5 to 3.1. (Note: In addition to Rest,dubbo in WebServices, Hessian, HTTP Invoker and other protocols are based on this HTTP remoting system). upgrade Spring: Upgrade the spring in Dubbo from 2.x to the most commonly used 3.x version, reducing the hassle of version conflicts in your project. Upgrade the Zookeeper client : Upgra

The example in this article describes how C # dynamically invokes events. In general, the traditional idea is to obtain information about the event through Reflection.eventinfo, then use the Getraisemethod method to get the method called after the event is triggered, and then use Methodinfo.invoke to invoke the event's dynamic invocation.Unfortunately, the Reflection.EventInfo.GetRaiseMethod method always returns NULL. This is because the C # compiler does not generate metadata information about

A. Web Service1. Web Serviceis a cross-language call between applicationsFor example, the weather forecast web Service:http://www.webxml.com.cn/webservices/weatherwebservice.asmx2. Wsdl:web Service Description Language (Web Service Description Language)The XML format describes how the called address method is called, and can be seen as a webservice instructionFor example, the weather forecast for: http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl3. Soap:simple Object Access Protoc

See the explanation of this. NET remote call, feel good, take to share!!. NET is available in two ways for remote invocation: WebService and Remoting.There is no essential difference between the principle of implementation and the following differences in the application development level: Remoting can flexibly define the protocol on which it is based, and if it is defined as HTTP, it makes no difference to the Web service, and generally pref

Cglib dynamically generated subclass, when the normal proxy class, which is why the creation of two objects. Shows the actual invocation procedure of spring's AOP proxy class:Therefore, as can be seen from the above analysis, MethodB is not notified by the Aopproxy, resulting in the end result is: The spring AOP enhanced class, in the same class's internal method invocation, its called method on the enhanc

Recursive invocation and dichotomy 1, recursive invocationRecursive invocation: The function itself is called directly or indirectly during a call to a function.Example: def Age (N): if n = =1 :return # End condition return Age (n-1) +2 # call the function itself print (age (5)) printing results 26Recursive execution is divided into two stages:1 recursion2 BacktrackingExample diagramRecu

Recursive invocation is a special form of invocation, which means that the method calls itselfpublic int method (int num) {if (num==1) {return 1;} else {Return Num+method (num-1);}}Description: The Main method calls methods (5), in method methods The parameter is not equal to 1, then call Method (4), until the parameter equals 1, then return. In this example, the parameter equals 1 o'clock, returns 1 to Met

Previous essays our access to other microservices is through some of the template methods provided by the Ribbon components to access, the use of the process will find a problem is that the invocation of a service interface is often not a place, so we need this service interface for a package, the other place Unified call this package, And each package is actually the use of Resttemplate template method to the target service interface calls, so the co

Java RMI refers to remote method invocation (invocation). It is a mechanism that enables an object on one Java virtual machine to invoke a method on an object in another Java virtual machine.Any object that can be called with this method must implement the remote interface. Java RMI is not a new technology (in the era of Java1.1), but it is a very important underlying technology.The famous EJBs are built on

Referring to method calls, I think most people's first reaction is to execute a method Bai, in fact, in the eyes of the virtual machine method call is only to determine which method he is going to call, and the implementation of the method is still a relatively large difference. The operation of any sequence is inseparable from the invocation of methods and the execution of methods, But learning in the JVM: a summary of runtime stack frames in a virtu

then serialized to the client. The client receives the object instance of the stub class of the WebLogic implementation class of the remote interface, and the method invocation of the object instance (in the client code is actually a call to the remote interface), The skeleton class object that will be routed to the WebLogic implementation class of the server-side remote interface, and the Skeleton class object calls the WebLogic implementation class

Dynamic (C #) dynamic invocation of class members with reflection Invoking a class member dynamically using reflection requires a method of the type class: InvokeMember. The declaration of the method is as follows (excerpt from MSDN): public Object InvokeMember ( String name, BindingFlags invokeattr, Binder Binder, Object Target, Object[] Args ); Parameters Name String that contains the name of the constructor, method, property, or field
